It's been a decade since Bruce Wayne hung up his cape, following most of the other superheroes who had been forced into retirement. Facing the downside of middle age, a restless Bruce Wayne pacifies his frustration with race cars and liquor – but the bat still beckons as he watches his city fall prey to gangs of barbaric criminals known as The Mutants.

The return of Harvey Dent as Two-Face finally prompts Wayne to once again don the Dark Knight's cowl, and his dramatic capture of the villain returns him to crime-fighting – simultaneously making him the target of law enforcement and the new hope for a desolate Gotham City. Particularly inspired is a teenage girl named Carrie, who adopts the persona of Robin and ultimately saves Batman from a brutal attack by the Mutant leader. Armed with a new sidekick, and re-energized with a definitive purpose, the Dark Knight returns to protect Gotham from foes new...and old.
